Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

An integral criterion of ignition in the inhomogeneous plasma of a toroidal reactor is obtained. The possibility of using this criterion for burn control in a reactor operating near ignition with a high energy gain is demonstrated by means of numerical modeling. The existence of an ignition scenario with decreasing temperature before ignition is demonstrated and explained. It is shown that a temperature profile near the unstable steady-state profile can be achieved by the appropriate choice of auxiliary heating characteristics. A method of continuous operation, based on weak modulation of the heating power, is proposed.
